The installation of rotary joints should be properly installed in accordance with the specifications. Otherwise, the sealing performance and service life are not fully realized.
1. One-way rotating joints and associated equipment, assembly and installation When the hollow shaft and the rotating body are connected by screwing, generally white lead oil or soft film is coated on the threads, and the tool clamps the clamping shaft (usually using wrenches) Mouth flat) The center screw of the threaded hole on the rotating body, tightly.
When the hollow shaft is equipped with a rotating and flanged connection, the thickness of the hollow shaft should be uniform at the protruding flange end of the washing machine, and equipped with a rotating body mating end section and screw holes, fixing bolts, fastening bolts, and coping angle fastening The final tightening torque should be the same.
2. It is the same one-way rotary joint as the two-way fixed inner pipe rotary joint and the rotating body and the outer pipe. The difference is the inner tube installation.
The connection of the end cap of the inner tube and the rotary joint adopts a threaded connection of a tapered pipe thread, which is connected with the rotation direction of the rotating body in the opposite direction and is connected with the outer pipe thread or the rotating body in the same rotation direction. The outer pipe is flanged, the inner pipe and the end cap are connected by threads, and sometimes one nut locks the end cap of the inner pipe.
When the mounting pipe includes the outer pipe end hole, screw inwards toward the positive rotating joint cover cap screw, then the inner pipe and rotating body, if using siphon type, the positive siphon bend pipe should be adjusted, and then the outer pipe and the matching rotating body fixedly assembled connection.
3, two-way rotating inner tube and outer tube rotary joint and rotating body assembly connection unidirectional rotary joint, the difference is the inner tube installation assembly.
Installed in the outer tube, inner tube and with rotating body components. The internal structure and the matching rotating body are generally threaded, and the rotation direction is opposite to that of the rotating body.
Remove the end caps of the swivel joints, when the inner and outer tubes are packed with packing seals, packing glands, stop pins (some rotary joint design parts) are removed, try different loose packings, fills or removes, then go to inner tube outer tube The center is loaded and the rotating body of the outer tube is fixedly connected. Then, according to the original open sequence reversed inner tube packing gland, the end cap assembly.
4. Do not do the following work before connecting with the fluid transport pipe fittings:
Rotate the connector housing with your hand or a tool wrench to check if it turns flexibly, or find out the cause and adjust.
With the design of ball bearings and the addition of lubricating grease and drainage holes, it should be checked whether there is hole up, drain hole, and jam by checking the filling cup during the conveying process.
Check and adjust the position of the fluid entering or extracting tube and the corresponding channel of the rotary joint to meet the design requirements.
The rotating joints of the assembly were rotated to stop and the lifting structure of the load-bearing structure was adjusted, and the concentricity of the housing and the hollow shaft was adjusted.
5, according to the rotary joint installation of manual assembly of the connection of the metal hose (or other flexible hose) and other related accessories, fluid transfer pipe connection fixed.
A training chair is a seat designed specifically for activities such as training and meetings. It has the characteristics of comfort, durability, and ease of movement, which can meet the needs of different groups of people. Training chairs can be classified into various categories based on material, structure, function, and other aspects. Below will be a brief introduction to the classification of training chairs.
1. Material classification
The materials of the training chair mainly include metal, plastic, and fabric. Metal training chairs typically have strong stability and durability, making them suitable for long-term meetings or training activities. The training chair made of plastic material has the characteristics of lightweight and easy to clean, making it easy to arrange the meeting site at any time and suitable for use in multifunctional halls and other places. The training chair made of fabric has a comfortable sitting experience and good breathability, making it suitable for long-term meetings or training activities.
2. Structural classification
The structure of training chairs mainly includes single chairs, linked chairs, and foldable chairs. Single chairs are the most common training chairs, with each seat being independent and adjustable as needed. Chainage refers to the connection of multiple seats together, usually in the form of one or more rows, suitable for use in large training venues. Stackable chairs are training chairs that can be folded and stacked, saving space and facilitating storage and handling.
3. Functional classification
The main functions of the training chair are adjustable, rotatable, foldable, and storable. The adjustable training chair can adjust the height and angle according to personal needs, providing a more comfortable sitting posture. The rotatable training chair can rotate 360 degrees, facilitating communication and interaction with people around it. The foldable training chair can be conveniently stored and transported, making it suitable for use in multifunctional halls and other places. The training chair that can store items is designed with storage space below or behind the chair, making it convenient to store items such as stationery and documents.
In summary, the classification of training chairs mainly includes material classification, structural classification, functional classification, etc. Choosing a suitable training chair can provide a better user experience and improve the effectiveness of training and meetings.
